How much detail was provided? Where was the information made public e.g website, paper?
Related to a cross sectional and/or intervention study.
Dear Mandy,
theoretically, the data analysis plan can be designed when the data collection instrument (questionnaire for ex.) is completed. According the research questions, the researcher should be able to know exactly what the required data analyses will be. Including descriptive analyses, bivariate ones and possibly multivariate ones.
That data analysis plan consists of a structured list of analyses to be conducted and generally refers to the question numbers. Something like this:
1/ Description of the sample: Q1; Q2; Q3
2/ Consumers behaviours: Q4;Q5;Q6 - Q4xQ1; Q5xQ1 etc. (X means that you make a comparative analysis - or cross tab)
3/ Opinions towards product: Q7 to Q14 - then Q7xQ3; Q8xQ3 etc...
4/ Segmentation: Classification (multivariate) with Q7toQ12
ETC.
Ideally the researcher should be able to circulate that plan to an IT person, performing the analyses with a software and delivering the results back to them.
Hope it helps. Kind regards.
Hello Mandy. My answer to your question is yes. The journal "Trials" welcome this kind of publication for RCT's, the reasoning behind is that it contributes to stressing the rigor in the design of such studies. A well design sampling scheme for a survey, in my view, would also merit publication. And moreover, I would advocate that any study should publish the design so that the researchers put it to scrutiny before they do the actual "field" work. So in Trials you can find many examples. I myself was involved in a very complex trial and we published the design in great detail. You can find ours in: https://trialsjournal.biomedcentral.com/articles/10.1186/1745-6215-15-219
